I have some fake plants in my bluey cages, they have never tried to eat them, they do constantly push them around and bury them, which is why I have never tried real plants. When I finish my new cage build for them I was going to try and find some more realistic looking ones and the ones I have now are very obviously fake. If I can't find any that I like I am going to just go with the rock and wood method that I used for my other reptiles.
